IPv6 Address

An IPv6 address consists of how many bits?​

128

Loopback address

A special IP address that can be used to verify that the TCP/IP protocol stack is properly installed on the host. The local loopback address is not assigned to an interface.

Anycast address

A unicast address assigned to more than one interface, typically belonging to different hosts.

Tunneling

Allows IPv6 hosts or sites to communicate over the existing IPv4 infrastructure.

Unicast address

An address assigned to a single interface for the purpose of allowing one host to send and receive data. Packets sent to a unicast address are delivered to the interface identified by that address.

Multicast address

An address that represents a dynamic group of hosts.

Stateful DHCPv6

Stateful DHCPv6 is the addressing mode in which the DHCP server provides each client an IP address, default gateway, and other IP configuration information (such as the DNS server IP address). The DHCP server tracks the status (or state) of the client.

Stateless DHCPv6

Stateless DHCPv6 is the addressing mode that uses the SLAAC process to obtain the IPv6 address, but uses the DHCPv6 server to receive other information such as the DNS server IP address.

Every device on the network must be assigned an IP address. With IPv6, each device can have multiple addresses types. Anycast

The anycast address is a unicast address that is assigned to more than one interface, typically belonging to different hosts. An anycast packet is routed to the nearest interface having that address (based on routing protocol decisions).

An IPv6 address can be assigned using any of the Assignment Methods described in the following table. 4.7.7 IPv6 Address Assignment Facts Static full assignment

The entire 128-bit address and all other configuration information is statically assigned to the host. The network administrator is responsible for manually configuring each individual device and updating any changes.

The first 48 bits of a Prefix?

The first 48-bits of the address define the site prefix. The site prefix defines the location of the address and is assigned by the local ISP.

Prefix ID

The first 64 bits of the IPv6 address. The prefix can be divided into various parts that identify things such as geographic region, ISP, network, and subnet.

In an IPv6 address, what do the first four blocks or 64 bits of the address represent?

The first 64-bits make up the prefix. The prefix can be divided into various parts that identify things such as geographic region, the ISP, the network, and the subnet.

Interface ID

The last 64 bits of the IPv6 address. This is a unique identifier for each device, similar to a MAC address.

Interface ID

The last 64-bits in the address is the interface ID. This is a unique identifier for each device, similar to a MAC address.

Every device on the network must be assigned an IP address. With IPv6, each device can have multiple addresses types. Loopback

The local loopback address for the local host is 0:0:0:0:0:0:0:1 (also identified as ::1 or ::1/128). The local loopback address is not assigned to an interface. It can verify that the TCP/IP protocol stack is properly installed on the host.

The next 16-bits after the first 48 in the prefix make up the ?

The next 16-bits make up the subnet ID. This defines the network that the device is connected to.

An IPv6 address can be assigned using any of the Assignment Methods described in the following table.4.7.7 IPv6 Address Assignment Facts Static partial assignment

The prefix is statically assigned, but the interface ID uses the modified EUI-64 format that is derived from the MAC address.

Every device on the network must be assigned an IP address. With IPv6, each device can have multiple addresses types. Unicast

Unicast addresses are assigned to a single interface for the purpose of allowing one host to send and receive data. Packets sent to a unicast address are delivered to the interface identified by that address. There are three types of unicast IPv6 addresses: link-local, unique, and global.

Interface

a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these.

Every device on the network must be assigned an IP address. With IPv6, each device can have multiple addresses types. Multicast

Multicast addresses represent a dynamic group of hosts. **There are no broadcast addresses in IPv6. IPv6 multicast addresses are used instead of broadcast addresses.

Wghat does the Prefix generally identify?

Because addresses can be allocated based on physical location, the prefix generally identifies the location of the host. The prefix is often referred to as the global routing prefix.

IPv6 adds features that are not available in IPv4. Auto-configuration

Because hardware IDs are used for node IDs, IPv6 nodes need only to discover their network IDs. This can be done by communicating with a router.

IPv6 adds features that are not available in IPv4. Built-in quality of service

Built-in support for bandwidth reservations makes guaranteed data transfer rates possible. Quality of service features are available as add-ons within an IPv4 environment but are not part of the native protocol.

What si the CIDR notation indicate?

CIDR notation is used to indicate the prefix-length. Just like in an IPv4 address, this indicates the portion of the address that is being used for the prefix (network address). ***To indicate the prefix length, add a slash (/) followed by the prefix length number. Full quartets with trailing 0s in the prefix address can be omitted (e.g., 2001:0DB8:4898:DAFC::/64).

An IPv6 address can be assigned using any of the Assignment Methods described in the following table. 4.7.7 IPv6 Address Assignment Facts Stateless address autoconfiguration(SLAAC)

Clients automatically generate the interface ID and learn the subnet prefix and default gateway through the Neighbor Discovery Protocol (NDP).

IPv6 adds features that are not available in IPv4 Built-in security features

IPv6 has built-in support for security protocols such as IPsec. IPsec security features are available as add-ons within an IPv4 environment.

IPv6 adds features that are not available in IPv4 Source intelligent routing

IPv6 nodes have the option to include addresses that determine part or all of the route a packet will take through the network. Nodes:An IP Address node is created in the datastore when a host, network device, printer, or SNMP managed device is scanned successfully

An IPv6 address can be assigned using any of the Assignment Methods described in the following table. 4.7.7 IPv6 Address Assignment Facts DHCPv6

IPv6 uses DHCPv6, an updated version of DHCP. DHCPv6 operates in one of two modes: Stateless and Stateful
